Nexen Arrowspeed CP661 vs BFGoodrich All-Terrain T/A KO2 — Compared

“I really like my KO2s. Great traction in wet/dry/gravel/dirt conditions, not noisy on the pavement, they wear very evenly and my current set is coming up on 32K miles. The tires had 15/32" tread depth when new, I'm down to about 8/32" left, minimum tread is 4/32" so they're good for a little while yet. Won't hesitate to buy another set when the time comes.”

“I ran the stock AT3’s on TH for about 5k miles with no issues. They were quiet and handled sand, small/medium rock gardens and steps fine - though I was pretty concerned about punctures in the rocks. They were excellent in rain and surprisingly good in light snow which is pretty rare here in TX. I switched to 285/75/17 AT3’s because I wanted more rubber and contact when airing down. I’ve never run the AT4’s so I can’t speak to their capabilities. I’ve run BFG KO2’s, KO3’s and MT’s on other vehicles and they are excellent off road. The KO2’s and MT’s were not great in rain, but you learned how to deal with them. The KO3 is superior to the AT3 off road IMO. The downside being it’s hard to find load ranges other than E. That was one of the reasons I stayed with AT3’s when I went to a larger tire. I could get it in load range C, I was confident it could handle the off road conditions I would use them in, and they were excellent on road. The majority of my use is on road so I tried to be realistic and factor that in to the selection - not that I don’t look at a set of 35” R/T Pro’s and think “I Want That”.”

“FWIW, I had the same 18s that you have and went to a 16" Vision Cross wheel and wrapped them in 225/70 KO2s. I weighed the stock wheels and the new wheels and the new set is only 2 pounds heavier than stock at most. I don't notice much acceleration loss, but I really don't beat on my jeep either. I did notice a little "hum" once I'm going 30mph but it's nothing annoying at all and I don't even hear it anymore. I have also carefully measured MPGs with both set ups and I have not lost anything. This is calculated MPG, not just what the computer says and I do add an additional 2.5% due to the increase in tire circumference. My avg is 25.1 (25.73 when adding the 2.5%) and my commute is 75% hwy and 25% local. I was afraid to get the KO2s because of added weight, tire noise and mpg loss, but I was afraid for nothing. Just my 2 cents, but I remember reading most people talk about how bad things would be with these tires. I'm glad I listened to those who said mpg loss would be minimal at most. Mike”
